Which of the following is considered a clinical contact surface when using traditional radiographic procedures?

1. Patient dental records

2. X-ray control panel

3. Floor beneath the dental chair

4. Outside door handles

The correct answer is: X-ray control panel

A Patient dental records are not considered a clinical contact surface when using traditional radiographic procedures because they are not directly in contact with the patient's mouth or body during the procedure. C: The floor beneath the dental chair is not considered a clinical contact surface as it is not directly involved in the radiographic process and is not in contact with the patient or equipment. D: Outside door handles are not considered a clinical contact surface as they are not involved in the radiographic process and are not in contact with the patient. The x-ray control panel, on the other hand, is considered a clinical contact surface as it is used to control the x-ray machine and is in direct contact with the patient's mouth or body during radiographic procedures. It is important to maintain proper infection control measures for clinical contact surfaces to prevent the spread of infection.
